Publication number: 20100331692Abstract: In one embodiment, an ultrasonic diagnostic apparatus includes an image creating unit, an image-creation control unit and a display control unit. The image creating unit creates an ultrasound image from data created by adding a reflected wave signal of an ultrasound wave transmitted to an imaging target portion of a subject by using a reception delay time calculated from a set sound velocity set as a sound velocity in the imaging target portion. The image-creation control unit switches a set sound velocity set at a present moment in a variable range, and controls the image creating unit so as to create a plurality of ultrasound images each using a reception delay time corresponding to each of the set sound velocities to be switched. The display control unit controls display such that the ultrasound images created are displayed on a certain display unit.Type: ApplicationFiled: June 28, 2010Publication date: December 30, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA MEDICAL SYSTEMS CORPORATIONInventors: Akihiro Kakee, Muneki Kataguchi, Kenichi Ichioka, Yasushi Kamewada

Publication number: 20080177182Abstract: A display controller causes a display to display a 3-dimensional B-mode image and a 3-dimensional colored Doppler image in a superimposed state. A marker generator generates three planar markers that are orthogonal to each other, and the display controller causes the display to display the three planar markers so as to be superimposed on the 3-dimensional B-mode image and so on.
